High-Intensity Interval Training Can Reverse Frailty at Advanced Age, Preclinical Study Finds

Updated August 30, 2017

Bruce R. Troen, MD, professor of medicine and chief of the Division of Geriatrics and Palliative Medicine, and Kenneth L. Seldeen, PhD, research assistant professor of medicine, have concluded a preclinical study that showed that brief periods of intense physical activity can be safely administered at an advanced age, and that this kind of activity has the potential to reverse frailty. “We know that being frail or being at risk for becoming frail puts people at increased risk of dying and comorbidity,” Troen said. “These results show that it’s possible that high-intensity interval training can help enhance quality of life and capacity to be healthy.”
